IN YOUR OWN WORDS what is the definition?
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
Answer:
Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.
Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes.
Anaphase is the stage of mitosis and meiosis in which the chromosomes move toward the poles of the spindle.
Telophase is the final stage of mitosis and of the second division of meiosis in which the spindle disappears and the nucleus reforms around each set of chromosomes.
Cytokinesis is the division of cells after either mitosis or meiosis I and II.

If both parents are black, which is a recessive trait, their offspring will be black. All of the 100% offspring will be black in nature, having the ff genotype. option 5 saying 100% is true for this.
How are the traits inherited?The traits are passed on from the parents to the offspring by sexual reproduction, which happens during the meiosis process. In the fur color of the dog, the dominant allele is F, which codes for the grey color, and the recessive allele is f, which codes for the black color.
The FF will show gray and the Ff will produce gray too, as the F is dominant over the f. Because it is recessive, the ff will have black fur.The cross of two purebred dominant (FF) parents will always form purebred gray offspring, and the heterozygous Ff parents will produce all types, such as grey and black offspring. The punnett square is explained below in the image.
As a result, all of the puppies will be black (ff) and 100% black.

In a breed of horse, the brown coat is codominant with a white coat. If the resulting offspring are heterozygous for coat color, what will be the phenotype of the offspring?
Answer:The coat will have both brown and white.
Explanation: Codominant traits are traits that both are both dominant, meaning they are both showing in the offspring if the offspring is heterozygous (meaning they have a mixed genotype ex: Bb or BW.)

Why is Replication important to YOU?
A. To make your proteins.
C. To destroy old cells.
B. To help you make more cells and grow.
D. To change your genetic code.
Answer: B to make more cells and grow.
Explanation:
This is because the primary purpose of DNA replication is to repair and replace old and damaged cells. If something goes wrong this can result in bad cell growths like cancer. DNA replication is also used in reproduction.

Species with which type of reproductive patterns are the most vulnerable to
extinction? Explain your
answer.
Answer:
Those species that are more vulnerable to extinction are the big-sized ones, that reach their sexual maturity in a relatively advanced stage of their lives and have a low growth rate per capita. They have a low reproductive rate.
Explanation:
There are specific heritable traits such as reproductive rate, trophic level, dispersion capability, that influence different species and their trend to be more or less vulnerable to extinction. "k" species have a low growth rate per capita, but they are big competitors with the capacity of displacing other species and monopolizing the available resources. These are big-sized species that live for a long time, reaching sexual maturity in advanced stages of their lives. They do not have numerous progenies, and hence, they spend a lot of time in parenting. Any environmental disturbance seems to severely affect them. These animals have a higher risk of getting extinct than those species with short-lived and elevated reproductive rates.
For many mammals and birds, this is a linear relationship. The bigger is the species, the more prone to get extinct it is.
Could someone help : how does the number of offspring that are produced by an individual typically compare with the fecundity of that individual? What factors create this (think of reproductive potential)
Answer:
The number of offspring produced is often related to the amount of parental care. Typically, the higher fecundity, the lower the amount of time parents devote to caring for the offspring.
The number of offspring that are produced by an individual typically varies with the fecundity, as the higher the fecundity, the lower the parental care per offspring, while a lower fecundity leads to more parental care.
What is parental care in the animal kingdom?Parental care refers to the behaviors of parents for the care of their offspring, and in the animal kingdom, parental care can take many forms, ranging from simple behaviors like providing food and shelter to more complex behaviors like teaching and training offspring and parental care is important for the survival and development of offspring, as it can improve an offspring's chances of survival by providing them with resources, protection, and guidance.
Hence, the number of offspring that are produced by an individual typically varies with the fecundity, as the higher the fecundity, the lower the parental care per offspring, while a lower fecundity leads to more parental care.

A. Anticodon
B. Amino Acid
C. tRNA
D. Codon
The name of the structure that is indicated by the arrow is known as Anti-Codon. Thus, the correct option for this question is A. This is because the codon is attached to the sequence of DNA.
What do you mean by Codon?A Codon may be defined as a particular sequence that consists of three consecutive nucleotides which significantly are the constituents of the genetic code and that encode a particular amino acid.
According to the context of this question, the given structure represents a tRNA molecule which is an adapter molecule. It is a clover-leaf-like structure that has five arms or loops.
They are anticodon loop that has bases complementary to the code. Amino acid receptor end to which amino acids bind. T-loop that helps in the binding of ribosomes. D-loop that helps in the binding of aminoacyl synthetase.

Does the rough ER or smooth ER send proteins on to the Golgi apparatus
Answer:
the rough Er because it has ribosomes on the surface
Explanation:
Answer: The rough ER sends proteins to the Golgi apparatus
Explanation:
The Golgi apparatus is considered "rough" because of the ribosomes on its outer layers. Ribosomes work with proteins, thus the rough Golgi apparatus would be the appropriate organelle.

Puromycin is an antibiotic. Its effect is to force the ribosome to detach from the mRNA chain before reaching the stop codon. Explain why this would have a harmful effect on a bacterium.
Answer:
Please find the explanation below
Explanation:
Transcription and translation are the two proocesess involved in gene expression. These two processes are important because the end result is a PROTEIN responsible for the phenotypic characteristics of that organism. Transcription involves synthesis of mRNA from DNA while translation involves synthesis of protein from mRNA.
In this question, an antibiotics called Puromycin forces the ribosome to detach from the mRNA chain before reaching the stop codon. This means that the antibiotics "Puromycin" abruptly truncates the translation process. Hence, proteins will not be produced. This means that the organism (bacteria) will not be functionally active because of lack of necessary PROTEINS.
